[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the appended Figure 1 to the appended Figure 7 drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0033] The existing bookmarks have relatively single functions. Usually, they only have the function of marking the reading progress. When readers are tired after long - time reading, there is an urgent need for a bookmark that can relieve fatigue.

[0034] In response to this, the applicant provides a projection bookmark, which not only has the function of marking the reading progress, but also can, when readers are tired after long - time reading, use its projection imaging function to increase the reading pleasure for readers.

[0035] Specifically, as Figures 1 to 3 shown, a projection bookmark of the technical solution of the present utility model includes a bookmark body 1. According to actual needs, the bookmark body is pre - designed with various contour shapes, such as the contour shapes of flowers, plants, animals, buildings, etc. Then the bookmark body 1 also has a hollow cavity 11 and a light - emitting structure 12, and the light - emitting structure 12 is assembled in the hollow cavity 11. The hollow cavity 11 is integrally connected to the bookmark body 1, and the contour shapes of the bookmark body 1, the hollow cavity 11, and the light - emitting structure 12 are the same and adapted. When one side of the bookmark is illuminated, the light passes through from one side of the light - emitting structure 12 to the other side of the light - emitting structure 12 and irradiates out, and forms a projection surface on the surface of the object being projected. The projection surface has the shape and pattern color of the bookmark. For example, if the bookmark is a bookmark in the shape of a colored flower, and then the bookmark is placed between sunlight and a book so that sunlight shines on the bookmark, then the shape and color of the flower of the bookmark will be projected on the book, making the book vivid and interesting, so as to relieve the fatigue of readers during long - time reading and also overcome the single function of the bookmark that only marks the reading progress.

[0036] Furthermore, as Figure 1As shown in the figure, a projection bookmark includes a bookmark body 1, and a hollow cavity 11 is provided on the bookmark body 1; a light-emitting structure 12 is assembled in the hollow cavity 11; the front and back sides of the light-emitting structure 12 can transmit light. When one side of the bookmark body 1 is illuminated, the light can pass through both sides of the light-emitting structure 12 and form an image on the other side.

[0037] Furthermore, the orthographic projection contour of the hollow cavity 12 presents various shapes; the shapes are preset graphic shapes.

[0038] Furthermore, as Figure 2 shown in the figure, the hollow cavity 11 has a contour line 111; the contour line 111 divides the hollow cavity 11 into several sub-hollow cavities 112.

[0039] It should be understood that, however, in order to make the image and color of the bookmark more rich and vivid, several contour lines 111 are provided on the hollow cavity 11. For example, for a leaf-shaped bookmark, several contour lines 111 are used to divide the hollow cavity 11 into sub-hollow cavities 112 with the shape of the vein patterns on the leaf blade. The contour shape of the sub-hollow cavity 112 matches the shape of the vein patterns on the leaf blade, so that the leaf bookmark is more vivid when projected and imaged.

[0040] What can be further more vivid is that several sub-hollow cavities 112 separated by the contour line 111 are assembled with the light-emitting structure 12. When the light-emitting structure 12 is green, this leaf bookmark can display the same green as the leaf when projected and imaged, so as to increase the realistic effect of this leaf bookmark.

[0041] The number of the sub-hollow cavities 112 is multiple. For example, in the embodiment of the leaf bookmark, in order to reflect the vein patterns on the leaf blade, this leaf bookmark has multiple sub-hollow cavities 112, and different sub-hollow cavities 112 are arranged at intervals or continuously.

[0042] It should be understood that, also in this embodiment of the leaf bookmark, as Figure 2 shown in the figure, taking the left-to-right direction as the X-axis and the top-to-bottom direction as the Y-axis, the sub-hollow cavities 112 are arranged continuously along the X-axis, and one sub-hollow cavity 112 is arranged above and below along the Y-axis respectively to form this leaf bookmark.

[0043] In another embodiment, as Figure 3 shown in the figure, for a flower-shaped bookmark, a single sub-hollow cavity 112 is nearly circular. One of the sub-hollow cavities 112 is designed to be placed in the middle, and several other sub-hollow cavities 112 are arranged at intervals around the sub-hollow cavity 112 placed in the middle, so as to form a bookmark with a flower shape.

[0044] Similarly, a pink light-emitting structure can be assembled in each of the sub-hollow cavities 112 in this embodiment, so that when the flower bookmark is illuminated, a pink flower is displayed on the surface of the object to be projected.

[0045] In some other embodiments, the spaced or continuous arrangement of the sub-hollow cavities 112 can be set on a bookmark body 1 at the same time, as long as it is beneficial to form the required pattern shape.

[0046] Furthermore, the cross-sectional areas of different sub-hollow cavities 112 are equal or unequal. For example, as Figure 4 shown, in the flower bookmark, the sub-hollow cavity 112 placed in the middle is slightly larger than the sub-hollow cavities 112 surrounding it, and several sub-hollow cavities 112 surrounding it are arranged in an equal shape and in an orderly manner to form a bookmark in the shape of a flower.

[0047] The sub-hollow cavities 112 in this technical solution are not limited to the above layout, and any layout in which the sub-hollow cavities 112 are presented in any shape or partially overlap is within the protection scope of this technical solution.

[0048] In order to make the bookmark body 1 fit the book more closely when placed in the book, further, as Figure 4 shown, the hollow cavity 11 and the sub-hollow cavity 112 are coaxially arranged and the end surfaces of their respective side walls are on the same horizontal plane, as shown in B.

[0049] It should be understood that the coaxial arrangement of the hollow cavity 11 and the sub-hollow cavity 112 means that the sub-hollow cavity 112 is placed inside the hollow cavity 11, and the end surface of the side wall of the sub-hollow cavity 112 is flush with the end surface of the side wall of the hollow cavity 11 at B, so that the surface of the bookmark body 1 is in a flat style, so that when the bookmark is placed in the book, the book paper will not be worn due to unevenness.

[0050] Furthermore, in order to make the color of the projected pattern of the bookmark closer to the color of the bookmark body 1, the light-emitting structure 12 uses a light-transmitting color oil. In some other practical applications, the light-emitting structure 12 also includes a PC film or a pet film, etc., as long as it is a light-transmitting material.

[0051] In this example, a light-transmitting color oil is used. Specifically, the light-transmitting color oil is introduced into the sub-hollow cavity 112, and then waiting for the light-transmitting color oil to dry and form a light-transmitting film. The color of the light-transmitting color oil is various and can be adjusted according to actual needs.

[0052] Since the light-transmitting color oil after film formation has a certain thickness, in order for the light-emitting structure 12 to be placed in the hollow cavity 11 after film formation and not to be exposed from the hollow cavity 11, the hollow cavity 11 for assembling the light-emitting structure 12 needs to have a certain height.

[0053] And since the aforementioned hollow cavity 11 and the sub-hollow cavity 112 are coaxially arranged and the end surfaces of their respective side walls are on the same horizontal plane, it should be understood that the side wall heights of the hollow cavity 11 and the sub-hollow cavity 112 are flush with each other. Therefore, whether it is the hollow cavity 11 or the sub-hollow cavity 112, when assembling the light-emitting structure 12 respectively, as Figure 5 shown, the thickness d of the light-emitting structure 12 is less than or equal to the wall height H of the hollow cavity 11 or the sub-hollow cavity 112.

[0054] Furthermore, as Figure 6 shown, the light-emitting structure 12 is assembled between 1 / 3 and 2 / 3 in the height H direction of the hollow cavity 11.

[0055] It should be understood that placing the light-emitting structure 12 between 1 / 3 and 2 / 3 in the height H direction of the hollow cavity 11 is beneficial to protecting the two side surfaces of the light-emitting structure 12, avoiding the two side surfaces of the light-emitting structure 12 from being scratched during the daily use of the bookmark, which affects the imaging clarity of the bookmark during projection.

[0056] However, in order for the projection imaging details of the bookmark to be clearer, further, the cross-sectional area of the sub-hollow cavity 112 is not less than 2 mm 2 .

[0057] It can be understood that when the pattern shape of the bookmark is relatively complex, the cross-sectional area of the sub-hollow cavity 112 is not less than 2 mm 2 . This is beneficial to the contour shape of the sub-hollow cavity 112 being clearly imaged after the bookmark is illuminated. If the cross-sectional area of the sub-hollow cavity 112 is too small, then after the bookmark is illuminated, the projected imaging graphic contour will not be clear and will be displayed as a black dot, which affects the projection effect of the bookmark.

[0058] In order to avoid dust accumulation at the joint of the sub-hollow cavity 112 or the hollow cavity 11 and the light-emitting structure 12 during the long-term use of the bookmark, which not only affects the beauty of the bookmark but also the projection imaging effect of the bookmark.

[0059] Therefore, as Figure 7As shown, further, the cavity wall of the hollow cavity 11 intersects with the surface of the light-emitting structure 12 at an angle A; the angle is an obtuse angle. It should be understood that setting the intersection of the cavity wall of the hollow cavity 112 and the surface of the light-emitting structure 12 at an obtuse angle is beneficial to facilitating the cleaning of the dust at the obtuse angle, facilitating the maintenance of the bookmark by the reader during daily use, so as to maintain an effective projection imaging effect. Similarly, this method is also applicable to the sub-hollow cavity 112, and will not be elaborated here.

[0060] In summary, a projection bookmark of the present technical solution includes a bookmark body 1. When one side of the bookmark is illuminated, the pattern of the bookmark can be imaged on the other side of the bookmark on the projection surface, so as to image an image that is consistent with the pattern, shape, and color on the bookmark, thereby solving the technical problem that the existing bookmark only has a single function of marking the reading progress.
